During the WW2, a Swiss mountain farmer, refuses to follow the government policy to increase self-sufficiency with produce. In his opinion, the steep mountain pastures are not suited for agriculture.

Even after all his fellow farmers have given in and have started to plant cops, Tanner continues his opposition and ignores all letters and instructions. This leads to a series of reprimands, for instance, some of his hay is seized and his wife cannot buy at the local grocer's since the family won't comply with the government policy.
